sapne ya svapn ate kyon hai?
is prashn ka koi thos pramanik uttar aj tak khoja nahin ja saka hai. prayah yah mana jata hai ki svapn ya sapne ane ka ek karan 'nind' bhi ho sakta hai. vigyan manta hai ki nind ka hamare mastishk men hone vale un parivartanon se sanbandh hota hai, jo sikhne aur yaddasht barhane ke sath-sath mans peshiyon ko bhi aram pahunchane men sahayak hote hain. is nind ki hi avastha men nyuron (mastishk ki koshikaen) punah sakriya ho jati hain. vaigyanikon ne nind ko do bhagon men banta hai pahla bhag ar i em arthat raipid ai muvment hai. (jismen adhikatar sapne ate hain) ismen sharir shithil parantu ankhen teji se ghumti rahti hain aur mastishk jagrat avastha se bhi jyada gatishil hota hai. is ar i em ki avdhi 10 se 20 minat ki hoti hai tatha pratyek vyakti ek rat men char se chah bar ar i em nind leta hai. yah sthiti nind ane ke lagabhag 1.30 ghante arthat 90 minat bad ati hai. is adhar par ganna karen to ratri ka antim prahar ar i em ka hi samay hota hai (yadi vyakti samanyatah 10 baje rat sota hai to ) jisse sapnon ke ane ki sanbhavna barh jati hai.
sapne bante kaise haiainn :
din bhar vibhinn sroton se hamare mastishk ko sfuran (signl) milte rahte hain. prathmikta ke adhar par hamara mastishk hamse pahle udhar dhyan dilvata hai jise karna ati jaruri hota hai, aur jin sfuran sandeshon ki avashyakta turant nahin hoti unhen vah apne men darj kar leta hai. iske alava pratidin bahut si bhavnaon ka bhi ham par pratyaksh prabhav parta hai. jo bhavnaen ham kisi karan vash daba lete hain (gussa adi) vah bhi hamare avchetan mastishk men darj ho jati hain. rat ko jab sharir aram kar raha hota hai mastishk apna kam kar raha hota hai. (is dauran hamen chetnavastha men koi skuran sanket bhavnaen adi nahin mil rahi hoti) us samay mastishk din bhar mile sanketon ko lekar sakriya hota hai jinse svapn pradarshit hote hain. yah vah svapn hote hain jo mastishk ko dinabhar mile sfuran, bhavnaon ko darshate hain jinhen dinmen hamne kisi karan vash rok liya tha. jab tak yah pradarshit nahin ho pata tab tak bar-bar najar ata rahta hai tatha in par niyantran chahakar bhi nahin kiya ja sakta.
